Application filed September 22, 1919. Serial No. 325,338.

To all whom it may concern:

Be it known that I, AUGUST SoHArFER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Room Ventilators, of which the following is a specification.

The object of this invention, generally, is to provide a simple, economical and efficient device for Ventilating a room, one of the special objects being to provide a device which shall automatically shift when the wind shifts to direct the air into the room.

The invention is embodied in the example herein shown'and described, the features of novelty being finally claimed.

In the accompanying drawing- Figure 1 is a perspective view of the device showing it applied to an ordinary house window. v

Fig. 2 is mainly a plan view of the same partly section.

In the views 5 and 5 designate a pair of isosceles triangular frame pieces of like form and equal dimensions arranged one above the other. Connecting the bases of these triangular frame pieces is a closed wall 6. The structure thus formed is pivoted upon a rod 7 at the apices of the triangular frame pieces between the window sill 8 and a cross piece 9 goes to be capable of freely oscillating from one side to 'the other of the window opening.

The vertical edges of the wall 6 are pro vided with considerable flanges 6 and 6 so that when the wind shifts pressure in these pockets causes the wall 6 to reverse it position with reference to the window opening as indicated by broken lines Fig. 2. The pieces 5 and 5 can be open frames but I prefer to make them closed so that the whole device shall form a pocket adapted to gather and direct the air into the room as indicated by the arrow Fig. 2. The device is particularly useful in connection with screened windows which tend more or less to make rooms hot and stuffy.

The form and application of the device can be changed without departing from the gist of the invention as claimed.

What I claim is:

1. A ventilator for a window, comprising,

in combination, closed rigid triangular top and bottom frames, an imperforate air deflectingwall connecting one pair of the corresponding edges of said frames, and means for pivoting said triangular frames at the angles thereof opposite the imperforate wall.

2. A ventilator for a window comprising, in combination, triangular top and bottom frames, an imperforate air deflecting wall connecting one pair of the corresponding edges of said frames, said wall being provided with vertical flanges, each projecting outwardly in the direction of the plane of the adjacent open side of the ventilator, and means for pivoting said triangular frames at the angles thereof opposite the imperforate wall. 7

AUGUST SCHAFF-ER.
